What sort of date plan did you have or not have going into this?
You ideally should have a plan for where you're gonna go and overall what topics or stories you're going to use.
Also keep the stack in mind and where you're getting stuck on it:
attraction
qualification
comfort
sexcalation
Did you try seeding any place where you coudl take her and be alone with her? (dvd room is probably ur best option).
Go on some more dates so you have a better comparison and can find ur weak spots.
Good job on writing the FR and going on the date, don't be afraid to add more detail.
If you find yourself getting stuck on what to say, have some prepared routines to fill in the gaps.
